IMPROVEMENT IN PRAIRIE-FLOWS.

Specification forming part of Letters Patent No. 16,216, dated December 9, 1956.

To all whom it may concern Be it known that I, MARsHALL TURLEY, o Galesburg, in the county of Knox and State of Illinois, have invented certain new and use ful Improvements in Prairie-Flows; and 1 do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, in which- Figure 1 represents a central vertical section. Fig. 2 represents a top plan. Fig. 3 represents a perspective view of the moldboard, cutter, and standard from one side. Fig. 4 represents a similar view from the opposite side.

Similar letters, where they occur in the several figures, denote like parts.

The nature of my invention relates to the arrangement of the mold-board, cutter, and standard with a view of reducing the usual friction upon the plow, so that a wider furrowslice with less team may be turned over than with any other plow ofthe kind of which I have knowledge.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawings.

A represents a pair of supporting-wheels on an axle, B, so as to form a truck, upon which the plow is arranged. O is the beam of the plow, which is united to the axle B at one side of the center of said axle, as seen in Fig. 2, for the purpose of preventing the tendency of the plow from running out of ground, and to'equalize draft.

Over the beam where it crosses the axle is placed a drivers or conductors seat, D, and at the point of the beam is attached a tongue, E and double-trees F, to which the horses or oxen may be hitched.

In rear of the drivers seat D, and behind the axle, a mortise is out through the beam, through which passes the standard G of the plow. On the front edge of the standard G are rack-teeth a, into which the teeth of a coggcd wheel, I), on a crank-shaft, c, suitably supportedin pillar-blocks d on the beam. By means of a crank or winch on said shaft 0 the standard and plow attached to itmay be raised or lowered to transport the plow from place to place, or to adjust it to the proper depth of furrow, and when thus-raised or lowered is held firmly in position by the lock-bolt 6 taking into the rack-teeth a on said standard.

H is the mold, which rises and at the same time curves from point to heel; and I represents what may be termed the share of the plow, it being, however, much smaller than plowshares in general. The landside of the standard G is set inside of the point of the plow, as not to touch the face of the land, and thus to avoid the customary friction at that point, and where the curve of the mold-board meets the standard the latter is cut away, so as to prevent but a thin edge and a curved surface, against which the furrow-slicemoves.

On the land side of the standard is an angular-shaped cutter, K, which almost meets the mold-board in a point a few inches behind the point of the plow. The vertical side of this cutterfserves the purpose of the ordinary bar to make leverage behind the plow, to hold it steadily to its work, and the horizontal part of it, g, running back in wedge form or like a wing, cuts under the land, and not only holding the truck, plow, and all down to its work, but cuts under for the next furrow-slice. The vertical edge of this cutter also falls within the extreme outside point of the mold-board, and thus I accomplish what is so desirable--viz., the so adapting of the standard to the plow as that it shall not offer resistance to the furrow. I am able to dispense with one-half of the team usually employed in drawing such a plow, and have, of course in saving so much power, made an arrangement of parts not heretofore used or known to me.

J is a cutterwheel which runs in advance of the plow, to cut the sod or soil vertically, and thusenable the mold-board to do less work, my whole object being to obviate the impact between the furrow-slice, land, and plow, and to relieve the team from labor, which is more incident to the bad construction of the plow than to the real difficulty of turning the furrow.

Having thus fully described the nature of my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

The arrangement of the standard, moldboard, and side cutter, K, with regard to each other and to the other parts of the plow as that they will operate as herein set forth and explained.

MARSHALL TURLEY.
